Elastic coefficients and moduli for cubic silicon carbide (β-SiC), corundum (α-Al₂O₃), and a tourmaline crystal (Schorl) The compressibility, tensile strength, and mechanical resistance to shear of a solid are related to the corresponding moduli (bulk, Young’s, and shear modulus), which are derived from the coefficients of elasticity.
28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.

The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.
Due to this limitation, today''s SiC substrates are manufactured with a gas phase method that can produce 4H-SiC bulk single crystals. Sublimation takes place at temperatures of at least 2,300 °C. Stresses associated with the high temperatures, and cooling down from them, give rise to thermal stress.
